The Sikky 370Z Quick Change Rear Kit is a vital addition when building a race car for top-tier performance. This setup allows users to change gear ratios in under 5 minutes simply by removing the rear cover. This is a massive advantage when tuning your setup at the track to ensure your gearing is in the sweet spot and you aren't forced to shift at inappropriate times. It is also designed to handle massive amounts of power. Our customers are using this setup in cars making well over 1,200 horsepower.
We designed, developed, and tested our subframe kit to withstand the most punishing conditions. Using advanced technology such as FARO 3D scanning arms and Solidworks CAD software, we design and build every subframe assembly to precise tolerances. Perfect rear alignment ensures the differential is always centered to achieve optimal CV joint angles while remaining Formula Drift legal. It is designed to handle all the abuse high-horsepower cars can throw at it. The subframe ships fully assembled with the necessary brackets welded and the entire assembly powder-coated black. There are options to add a Sikky Winters IRS rear, Sikky solid subframe bushings, driveshafts, and/or heavy-duty axles. If you want a competitive edge, the Sikky Winters IRS subframe kit is the right choice.

Before Ordering
○ Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
○ Confirmation of Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will check for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our homepage, it does not necessarily mean they will fit Japanese models without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically on the checkout page when you enter your shipping address. For large items like body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us to confirm the delivery date in advance. Note that all items are transported via air freight. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation documents or similar paperwork for the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, packaging boxes and products may occasionally sustain shipping damage. Please understand that we will only handle returns, refunds, or exchanges for shipping-damaged items, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Furthermore, for products sold through us, we will only handle warranty-related issues "exclusively through us." Please note that we do not handle requests through other companies or distributors located within Japan.
